If solar is an economically viable alternative, you won't need government investment, there will be billions of private investment. It's not like solar technology appeared on the scene yesterday - it's been around as an alternative for years. Solar didn't provide a cheaper alternative when oil was $140.00 a barrel. What gives you reason to believe it will be more competitive when oil hits $60.00 a barrel in a couple of months absent government subsidies like the one in the bailout bill?

Your link hardly proved your case. It says due to capital being in low supply, Solar stock dropped, however, Goldman Saks said that solar will be a good investment in the future. Once again, you're thinking short term. Yes, solar has been around forever, no pun intended, but this country/world has never been in a situation where alternative energies investment is just a passing fancy for the greenies. It's a necessity.
The price of oil may continue to go down, especially if efficiency in alternative sources in years to come reach comparables oil prices . However, oil is a finite resource. What makes you think it will last forever with the population in this world? Pehaps when the government starts limiting your consumption, home sizes, how many children people can have, and mandates they go to military school so they can protect this country, people will then start to realize we should have invested in using all our alternate sources?
